The PCVA-KB7P/U (wired) Sony VAIO keyboard was officially used with the following model Sony VAIO computers:

VGCRA820G, VGCRA822G, VGCRA825G, VGCRA826G, VGCRA828G. It was also distributed with other model VAIOs like my later model VGC-RA837GY. This led to a lot of confusion about where to find the driver for the keyboard, because the only driver listed for my model is described as an "Original - Sony« Wireless Keyboard and Mouse Driver". My computer did NOT come with a "wireless" keyboard, it came with the PCVA-KB7P/U (wired) Sony VAIO keyboard. This driver is for an English language keyboard, unlike the other one available at this site. The other driver is for a Japanese keyboard and will not work with an English language keyboard like this driver will. Note though,

that this driver is ONLY for the Microsoft« Windows« XP Media Center Edition operating system, since some of the special keys on the keyboard only work with Media Center. I just installed this driver on my computer earlier today and for the first time, I'm able to use all the special function keys on my keyboard. Enjoy!

DriverGuide's installer software (Windows only) simplifies the driver installation process. It safely downloads and verifies your driver and then assists in the installation of it.

You may notice that the file size of the installer software is much smaller than the file size of your actual driver. The reason is that first the installer setup file is downloaded, and then the installer software does the work of fetching
your driver from our fastest download server.

The installer setup file has been certified safe by leading-class virus and malware scanners.

Sometimes anti-virus software can report false positives. If this happens to you, we encourage you to submit the file you download to VirusTotal (a free, independent service which identifies malicious content) where you will see dozens of other anti-virus scanners report the file is perfectly safe.

The installer setup file may include a purely optional advertising offer which you are free to decline. We only work with trusted advertising partners.
